Solution Overview

Problem

Current wound care compositions often struggle with effective delivery of collagen and antimicrobial agents to wound sites, leading to inadequate healing and increased infection risk.

Innovation Solution

An oil-based composition comprising micronized or powdered collagen and polar antimicrobial agents like PHMB, suspended in an oil-based carrier, which enhances penetration and absorption of collagen and antimicrobial agents into the wound site.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If solid substrate collagen-based wound dressings are used, then wound coverage is provided, but penetration and absorption of collagen and antimicrobial agents into the wound site is insufficient

Engineering Contradiction:
Improvewound healing effectivenessVSAvoiddelivery efficiency of collagen and antimicrobial agents
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent transforms collagen from a solid substrate form into a micronized or powdered form suspended in an oil-based carrier. This parameter change in physical state and particle size dramatically improves penetration and absorption into the wound site while maintaining wound coverage functionality.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces an oil-based carrier as an intermediary medium to deliver both collagen and polar antimicrobial agents (like PHMB) to the wound site. This intermediary solves the incompatibility between solid collagen substrates and effective antimicrobial delivery by creating a unified suspension system that penetrates wounds effectively.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If traditional wound care compositions are used, then basic wound coverage is achieved, but delivery of collagen and antimicrobial agents to wound sites is ineffective

Engineering Contradiction:
Improveamount of collagen and antimicrobial agents deliveredVSAvoidhealing acceleration rate
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The patent creates a composite wound care composition combining micronized/powdered collagen with polar antimicrobial agents (such as PHMB) suspended in an oil-based carrier. This composite formulation ensures both substances are delivered together in effective quantities directly to the wound site, simultaneously achieving high substance delivery and accelerated healing productivity.

Inventive Principle:
Principle #40Composite materials

3Strength

If solid substrate collagen dressings are used, then structural support is provided, but absorption and penetration into the wound bed is limited

Engineering Contradiction:
Improvestructural integrity of dressingVSAvoidpenetration speed into wound site
Core Design Contradiction:
StrengthVSSpeed

Solution Approach 1:

The patent segments collagen into micronized or powdered particles instead of using solid substrate forms. This segmentation increases surface area and reduces particle size, enabling rapid penetration and absorption into the wound site while the oil-based carrier maintains cohesive delivery of the segmented collagen particles.

Inventive Principle:
Principle #1Segmentation
